Add emulation of HP PA-RISC.
System and user emulation of HP's PA-RISC platform. Both 32-bit (PA1.1) and 64-bit (PA2.0). Emulated systems would likely include one of the 'Snakes' (e.g. the 715/100), the C180/C240/similar, and C3000 or similar.
Instruction decoding, branching and most simple instructions are emulated.
The code is currently kept in a separate git repository:
